ISO-BLOCO One is a special multi-functional all-in-one joint sealing tape with outstanding properties. Having a revolutionary low a-value of Zero the pre-compressed tape is 100 % airtight at the internal seal area, contributing enormously in minimising heat loss by convection. It also possesses an optimal vapour diffusion gradient from the inside outwards (50:1) enhancing the external transmission of moisture, enabling the joints to dry out quicker.
Having an exceedingly high movement accommodation factor (500 %) and an extraordinarily high driving rain resistance with a minimum of 1,000 Pa (greater than Hurricane Force 12) it outperforms conventional impregnated sealing tapes.

This all-in-one PUR-flexible foam sealant tape combines all the requirements of the energy savings regulations (EnEv), the RAL installation instructions and the UK Building Regulations in one product. It is particularly suitable for the reliable, uncomplicated and time saving perimeter sealing of windows and doors. This intelligent joint sealing tape functions around the 3-level-principal. Externally it provides high resistance to driven rain, within the middle area it provides thermal and acoustic insulation and internally it is absolutely airtight as well as a water vapour barrier.
